Built for performance and reliability, the benchtop Spectrophotometer CM-3700A is a top-of-the-line measurement instrument designed to precisely evaluate the color and appearance of opaque, transparent, translucent, and fluorescent samples. This high precision, versatile spectrophotometer is used to evaluate, reproduce, and help control the color and appearance of samples in a more effective, streamlined process. Its advanced capabilities and unwavering performance enable users to formulate and match color quality standards more efficiently, maintain consistency in each batch of material, and help communicate color seamlessly internally and throughout the supply chain. This makes the CM-3700A ideal for color analysis, formulation, and quality control inspections within laboratory and manufacturing environments.

The benchtop Spectrophotometer CM-3700A is compatible with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis, as well as Colibri software to formulate color recipes for various applications and share real-time measurement data.
